Do the file sizes look normal? Did the download complete?
Both of those things check out for me. I've tried all I can think of.
UPDATE: I restarted my PC and the installer finally ran. But then a new problem sprung up. My install "ended prematurely" The window said this exactly: "Microsoft Xbox One Controller for Windows Setup Wizard ended prematurely because of an error. Your System has not been modified. To install this program at a later time, run the Setup Wizard again. Click the Finish button to exit the Setup Wizard."
